Description
The invention concerns a holder for detachably fastening of a flat,
approximately rectangular device like a tablet computer or a
smartphone to a component, in particular a component of a motor
vehicle, wherein the holder comprises a holding mechanism for
detachably holding the device and a fastening element that is
connected to the holding mechanism to connect the holder with the
component, wherein a rotary bearing is provided that is rotatable
around an axis of rotation, wherein the rotary bearing is connected
to the holding mechanism, and wherein a pivot bearing is provided
which is connected to the rotary bearing and which is connected to
the fastening element. The invention also concerns a fastening
fixture that comprises such a holder.
Such holders are known from the state of the art, e.g. from EP 2
528 781 B1. In such a holder known from the state of the art, the
rotary bearing is indirectly connected to the pivot bearing via a
second rotary bearing, thus providing a sort of "con rod solution"
with which the holder or the device attached to the holder can be
pivoted between two usage positions. In this context, it is
possible to fasten this holder into a socket of a motor vehicle by
means of a suitable fastening element, or for example to fasten the
holder indirectly onto the headrest rods of a motor vehicle with a
suitable fastening element.
However, these holders have not always performed well when fastened
to the headrest rods, in particular with regard to large tablet
computers of the new generation that in a view from above often
exceed the size of an A4 sheet of paper. On the one hand, a
vertical positioning of the tablet computer may be prohibited by
the "con rod" due to the proximity to the roof or the ceiling of
the motor vehicle.
On the other hand, the latest, particularly large tablet computers
also have display sizes of 13 inches or more. This tablet computer
size affects the weight of the tablet computer, which increases
accordingly. In the event of a crash the long lever arm of the con
rod known from EP 2 528 781 B1 is disadvantageous because of the
greater weight.
Therefore, the invention aims to provide a holder for detachably
fastening of a flat, approximately rectangular device like a tablet
computer or a smartphone to a component, in particular a component
of a motor vehicle, with which larger tablet computers can also be
fastened sturdily and securely.
This task is solved by a holder having the features of claim 1.
Advantageous embodiments are specified in the dependent claims.
The holder according to the invention is characterized in that the
rotary bearing comprises a first rotary bearing portion connected
to the holding mechanism and a second rotary bearing portion
connected to the fastening element, wherein locking elements are
provided on the rotary bearing perpendicular to the axis of
rotation of the rotary bearing, the locking elements being
displaceable between a radial inner locking position and a radial
outer release position, wherein in the release position the first
rotary bearing portion is rotatable in relation to the second
rotary bearing portion and wherein in the locking position the
first rotary bearing portion is fixed in relation to the second
rotary bearing portion, wherein an annular spring is provided which
is designed and arranged such that the locking elements are
pre-stressed in a radially inward direction into the locking
position by the annular spring. Preferably, the first and second
rotary bearing portions glide over one another when rotating around
the rotary bearing. It is possible for the annular spring to be
made from spring steel. However, it is also possible for the
annular spring to be made from a plastic material, in particular
from an elastically resilient plastic material. Advantageously, the
annular spring is arranged radially, i.e. perpendicular to the axis
of rotation of the rotary bearing, outside of the locking
elements.
According to a first advantageous embodiment, the holder comprises
the holding mechanism comprising a receiving portion for the device
and holder elements located in the region of the receiving portion
for holding the device, and the first rotary bearing portion is
located on the side of the holding mechanism facing away from the
receiving portion. Advantageously, the first rotary bearing portion
is directly connected to the holding mechanism, though it is always
connected or screwed to the holding mechanism in a torque proof
manner.
Advantageously, a connecting element is provided, wherein the
second rotary bearing portion is located on the connecting element
and wherein the connecting element comprises pivot bearing portions
of the pivot bearing. It is possible that pivot bearing
counter-portions are provided which are located on the fastening
element, wherein the pivot bearing portions and counter-portions
correspond to one another in such a way that the pivot bearing is
designed as a friction bearing.
Further, it is also advantageous when the first rotary bearing
portion is designed as a cone, wherein the second rotary bearing
portion is designed as a counter-cone. It has proven especially
advantageous when the cone and the counter-cone comprise an
identical inclination to the axis of rotation of the rotary bearing
and are arranged coaxially to one another so that the cone and the
counter-cone can glide over one another to realize the rotary
bearing during rotating.
In order to be able to enable an adjustment of a tablet computer or
a smartphone from portrait to landscape mode or vice versa and to
lock the holder in the respective position, it has proven
particularly advantageous when at the first rotary bearing portion
multiple, preferably 4, locking grooves are provided which are
arranged at regular distances from one another with respect to the
circumference of the first rotary bearing portion. If 4 locking
grooves are provided, it is particularly advantageous when the
locking grooves are arranged at a 90.degree. angle from one
another. If 4 locking grooves are arranged in a 90.degree. angle to
one another, only adjustment from portrait to landscape mode is
possible. If more than 4 locking grooves are provided in smaller
angled increments, locking in interim positions is also
possible.
According to a particularly advantageous embodiment of the holder,
the locking elements comprise locking portions that correspond with
the locking grooves such that the locking portions at least
partially engage into the locking grooves when in locking position.
For example, it is possible for the locking grooves to comprise a
locking groove profile, wherein the locking portions comprise a
locking portion profile that corresponds to a negative counterpart
of the locking groove profile.
It has proven particularly advantageous when the locking grooves
and the locking portions comprise a profile that is designed in
such a way that rotation of the first rotary bearing portion in
relation to the second rotary bearing portion results in a
displacement of the locking elements from the locking position to
the release position against the spring force of the annular
spring. According to an advantageous embodiment of the holder, the
locking grooves are designed as V-grooves, wherein the locking
elements comprise V-shaped locking portions that correspond with
the V-grooves. Rotating the first rotary bearing portion in
relation to the second rotary bearing portion thus causes the
V-grooves and V-shaped locking portions to slip around each other's
circumference. This sliding along the circumference pushes the
V-shaped locking portions radially outward against the spring force
of the annular spring (i.e. perpendicular to the axis of rotation
of the rotary bearing) and thus releases the locking grooves, so
that the locking elements can be displaced from the locking
position to the release position.
A particularly affordable and stable design of the holder includes
multiple, preferably 2 locking elements which are arranged in a
mirror symmetrical manner with respect to the axis of rotation.
It has proven especially advantageous when multiple, preferably 2
guide portions are provided on the second rotary bearing portion
for the locking elements which are arranged in a mirror symmetrical
manner with respect to the axis of rotation. Advantageously, the
guide portions are attached in a torque proof manner to the second
rotary bearing portion or are flush-cast into the second rotary
bearing portion, e.g. via plastic injection molding, wherein the
locking elements are guided in the guide portions. Because of the
guide portions being attached to the second rotary bearing portion
in a torque proof manner, the locking elements which are guided in
the guide portions can engage into the locking grooves to interlock
with the first rotary bearing portion such that the first rotary
bearing portion is fixed in relation to the second rotary bearing
portion.
In order to be able to guide the locking elements in a particularly
secure manner, it is proven advantageous when the guide portions
are designed to guide the locking elements. It is possible for an
inner profile of the guide portions to correspond perpendicularly
to the axis of rotation with an outer profile of the locking
elements.
According to a particularly advantageous embodiment of the holder,
the pivot bearing comprises a pivot bearing axis of rotation,
wherein the pivot bearing axis of rotation is located in a plane of
the first and/or second rotary bearing portion. In this way, a
holder can be provided wherein its rotary bearing and its pivot
bearing are realized in a particularly compact and space saving
manner such that a holder can be provided which has a reduced
overall size which can thus be mounted particularly closely to a
component, for example to the headrest rods of a motor vehicle.
The aforementioned task is also solved by a fastening fixture
having the features of claim 12. Such a fastening fixture includes
a holder according to at least one of the claims 1 to 11 and at
least one mounting fixture that comprises a receiving socket which
is designed for detachably fastening of the fastening element of
the holder.
According to a first advantageous embodiment of the fastening
fixture, the mounting fixture comprises a base part with a
receiving portion designed for being arranged at a tube-shaped
component, and the mounting fixture comprises a band-shaped
tensioning device designed for tensioning the mounting fixture at
the tube-shaped component by tensioning the tube-shaped component
between the receiving portion and the tensioning device.
Advantageously, an elastic, deformable insertion piece is located
in the receiving portion which may be made, for example, from
rubber or from a soft plastic. A tube-shaped component can thus be
used to easily and reliably fasten the mounting fixture onto the
tube-shaped component between the receiving portion and the
band-shaped tensioning device.
Advantageously, the band-shaped tensioning device includes a
hook-and-loop fastener and/or a cable tie and/or an eccentric
tensioning device.
According to another advantageous design of the fastening fixture,
the mounting fixture comprises a suction cup designed for being
fastened onto an even surface. Advantageously, the mounting fixture
includes a release lever usable for detaching the suction cup.
According to another advantageous embodiment of the fastening
fixture, the mounting fixture is designed for being fastened onto a
wall. It is possible for the mounting fixture to comprise a groove
stone-shaped fastening portion that comprises drill holes with
which the fastening portion or the mounting fixture can be fastened
onto a wall.
According to another particularly advantageous design of the
fastening fixture, it is possible that an extension piece is
provided that comprises a fastening element and a receiving socket,
the receiving socket being arranged away from the fastening element
with respect to an axial direction, wherein the receiving socket is
preferably arranged axially with respect to the fastening element.
The fastening element of the holder can thus be inserted into the
receiving socket of the extension piece, wherein the fastening
element of the extension piece can be inserted into the receiving
portion of the mounting fixture. This allows for an extension of
the distance between pivot bearing 32 and the receiving portion of
the mounting fixture, so that the fastening fixture can be better
adjusted to the respective mounting requirement.
Other features and advantageous embodiments of the invention can be
found in the following description, with which various designs of
the invention are described and explained in greater detail.
It is shown in:

FIGS. 1 to 4 show a first design of a holder 10 according to the
invention for detachably fastening of a flat, approximately
rectangular device not shown in the figures such as a tablet
computer or a smartphone onto a component, in particular a
component of a motor vehicle. FIG. 1 shows the holder 10 in a
perspective frontal view, whereas in FIG. 2, the holder 10 is shown
in a perspective rear view.
The holder 10 comprises a holding mechanism 12 for detachably
holding the device and comprises a fastening element 14 for
connecting the holder 10 with the component, e.g. with a
corresponding receiving socket in a motor vehicle or with a
fastening fixture known from EP 2 437 960 B1 for attaching to two
spaced apart headrest rods of a vehicle seat.
For anchoring the fastening element 14 the holder 10 comprises
detents 16 that can be unlocked with the push buttons 18. The
holding mechanism 12 comprises a receiving portion 20 for the
device and clamp-like holder elements 22a, 22b located in the
region of the receiving portion 20 for holding the device. As
readily apparent from FIGS. 1 and 2, the holding mechanism 12
further comprises in an upper portion a push button 24 that makes
it possible to displace the holder elements 22a, 22b relative to
each other in the direction of double-arrow 26, and accordingly
provide a size adjustment of the holding mechanism 12. However, the
holding mechanism 12 is part of a separate patent application and
will not be explained in further detail here.
The holder 10 comprises a rotary bearing 30 that is rotatable
around an axis of rotation 28 (see FIG. 4), which is connected to
the holding mechanism 12. The holder 10 also comprises a pivot
bearing 32 connected to the rotary bearing 30 that is connected to
the fastening element 14.
The rotary bearing 30 comprises a first rotary bearing portion 34
that is firmly connected to the holding mechanism 12 and which is
located on the side of the holding mechanism 12 facing away from
the receiving portion 20. The rotary bearing 30 also comprises a
second rotary bearing portion 36 that is connected to the fastening
element 14. The holder 10 comprises a connecting element 38,
wherein the second rotary bearing portion 36 is located on the
connecting element 38 and wherein the connecting element 38
comprises pivot bearing portions of the pivot bearing 32. The pivot
bearing 32 rotates around a pivot bearing axis of rotation 33,
which is arranged perpendicular to the axis of rotation 28 of the
rotary bearing 30.
The first rotary bearing portion 34 is shaped as a cone and the
second rotary bearing portion 36 is shaped as a counter-cone. The
two cones of the rotary bearing portions 34, 36 are coaxially
positioned to the axis of rotation 28. Four locking grooves 40 are
located at the first rotary bearing portion 34, and are arranged at
an angle of 90.degree. to one another around the circumference of
the first rotary bearing portion 34. The locking grooves 40 are
shaped as V-grooves.
As is particularly apparent from the sectional view of FIG. 3, the
two rotary bearing portions 34, 36 are connected via a screw 42 and
a nut 44. The screw 42 and the nut 44 are coaxially positioned to
the axis of rotation 28 of the rotary bearing 30 and are not shown
in the exploded view of FIG. 4 for improving clarity.
In order to provide a locking connection of the rotary bearing 30
or the first rotary bearing portion 34 to the second rotary bearing
portion 36, two locking elements are provided on the rotary bearing
30 perpendicular to the axis of rotation 28, the locking elements
being displaceable in the direction of the double-arrow 45 between
a radial inner locking position and a radial outer release
position. The locking elements 46 are arranged in a mirror
symmetrical manner with respect to the axis of rotation 28.
In the release position of the locking elements 46 the two rotary
bearing portions 34, 36 can be rotated with respect to each other,
wherein the rotary bearing portions 34, 36 are fixed against one
another when the locking elements 46 are in the locking
position.
To lock the two rotary bearing portions 34, 36 the locking elements
46 comprise locking portions 48 which are clearly visible in FIG. 3
and which correspond with the locking grooves 44 in such a way that
the locking portions 48 are at least partially engaged into the
locking grooves 40 when in locking position.
The locking portions 48 also comprise a V-shaped profile that
corresponds with the V-groove profile of the locking grooves
40.
The second rotary bearing portion 36 also comprises two guide
portions 50 that are arranged in a mirror symmetrical manner with
respect to the axis of rotation 28 and which guide the locking
elements 46, wherein these guide portions 50 are designed to guide
the locking elements 46. The guide portions 50 thus comprise an
inner profile perpendicular to the axis of rotation 28 that
corresponds with the outer profile of the locking elements 46 in
the direction of the arrow 45. Preferably an inner profile of the
guide portions 50 is thus only minimally larger than an outer
profile of the locking elements 46.
An annular spring 52 is located radially outside of the locking
elements 46, made from spring steel, designed and arranged so that
the locking elements 46 are pre-tightened radially inward by the
annular spring 52, i.e. in the direction of the arrow 54, into the
locking position.
The guide portions 50 are attached in a torque proof manner to the
second rotary bearing portion 36 respectively cast into the second
rotary bearing portion 36, e.g. via plastics injection molding,
wherein the locking elements 46 are guided within the guide
portions 50. Because of the guide portions 50 being attached to the
rotary bearing portion 36 in a torque proof manner, the locking
elements 46 which are guided within the guide portions 50 can
engage into the locking grooves 40 for locking with the first
rotary bearing portion 34 in such a way that the first rotary
bearing portion 34 is fixed in relation to the second rotary
bearing portion 36.
Because the locking grooves 40 and the locking portions 48 comprise
a V-shaped profile with slanted surfaces, rotation of the first
rotary bearing portion 34 in relation to the second rotary bearing
portion 36 in the direction of the arrow 56 leads to a relocation
of the locking elements 46 into the release position against the
spring force of the annular spring 52 by means of sliding of the
slanted surfaces of the locking grooves 40 and the slanted surfaces
of the locking portions 48 of the locking elements 46 along one
another.
The rotary bearing 30 is fully protected against dirt by a cover
58.
By means of the holder 10 according to the invention and because of
the direct connection of the rotary bearing 30 to the holding
mechanism 12, a particularly stable fastening even for tablet
computers with a size greater than 13 inches can be provided on the
one hand. On the other hand, because of the locking elements 46,
which are set into the locking position by the annular spring 52,
and because of the four locking grooves 40, an easy and secure way
of locking of the holder 10 in a vertical and horizontal mode is
provided.
FIG. 5 shows a second design of the holder 10 according to the
invention. Corresponding components and elements are marked with
the respective reference numbers. The holder shown in FIG. 5 is
able to pivot around the pivot bearing axis of rotation 33 of the
pivot bearing 32 in the direction of the arrow 60. Furthermore, as
explained above, the holder 10 can rotate by 360.degree. around the
axis of rotation 28 of the rotary bearing 30 in the direction of
the arrow 62. The pivot bearing axis of rotation 33 is arranged in
a plane 64 of the first and/or second rotary bearing portion 34,
36. In this way, a holder 10 can be provided, having a rotary
bearing 30 and pivot bearing 32 which can be particularly space
saving and compact, allowing for providing a holder 10 having a
reduced overall size which can thus be mounted particularly closely
to a component, for example to the headrest rods of a motor
vehicle.
FIGS. 6 to 10 show a first to fifth design of a detail of the
fastening fixture 66 according to the invention, comprising a
holder according to the invention and a mounting fixture 68.
Corresponding components and elements are marked with the
respective reference numbers. The mounting fixture 68 each
comprises a receiving socket 70 designed for detachably fastening
of the fastening element 14 of the holder 10. When the holder 10 is
arranged at the mounting fixture 68, the fastening element 14 is
completely engaged into the receiving socket 70 and the detents 16
are locked into locking openings 72 of the respective mounting
fixture 68.
The mounting fixtures 68 differ only in the manner of their
fastening.
The mounting fixtures 68 of the fastening fixtures 66 shown in
FIGS. 6 to 8 comprise a base part 74 with a receiving portion 76,
which is designed to be placed on a rod- or tube-shaped component
not shown in the figures. An elastically deformable insertion piece
78 that is made from rubber or from soft plastic is arranged within
the receiving portion 76.
The mounting fixtures 68 each comprise a band-shaped tensioning
device 80 designed to tension fix the mounting fixtures 68 onto the
tube-shaped component by tensioning the tube-shaped component
between the receiving portion 76 and the tensioning device 80.
Because of the elastically deformable insertion piece 78 a
tube-shaped component for fixing the mounting fixture 68 onto the
tube-shaped component can be particularly easily and reliably
clamped between the receiving portion 76 and the band-shaped
tensioning device 80.
The band-shaped tensioning device 80 each comprises a first and
second end 82, 84 with which it can be fastened onto the base part
74 of the mounting fixtures 68 on a side adjacent to the receiving
portion 76.
According to the design of FIG. 6, the band-shaped tensioning
device comprises a hook-and-loop fastener 86. According to the
design of FIG. 7, the band-shaped tensioning device comprises a
cable tie 88. According to the design of FIG. 8, the band-shaped
tensioning device comprises an eccentric tensioning device 90 with
a knee lever 92.
The fastening fixture 66 shown in FIG. 9 comprises a mounting
fixture 68, which is designed to being fastened onto a wall. This
mounting fixture comprises a groove stone-shaped fastening portion
94 that comprises drill holes 96, with which the fastening portion
94 or the mounting fixture 68 can be fastened onto a wall.
Furthermore, the fastening fixture 66 shown in FIG. 9 comprises an
extension part 98, that comprises a fastening element 100 identical
to the fastening element 14 and a receiving socket 102, the
receiving socket 102 being arranged away from the fastening element
100 with respect to an axial direction and being identical to the
receiving socket 70 of the mounting fixtures 68, wherein the
receiving socket 102 is preferably arranged axially with respect to
the fastening element 100. Furthermore, the extension piece
comprises detents 16 and locking openings 72. The fastening element
14 of the holder 10 can thus be inserted into the receiving socket
102 of the extension piece 98, wherein the fastening element 100 of
the extension piece 98 can be inserted into the receiving socket 70
of the mounting fixture 68. In this way, an extension of the
distance between the pivot bearing 32 and the receiving socket 70
of the mounting fixture 68 can be provided, such that the entire
fastening fixture 66 can be better adjusted to the respective
mounting requirements.
Concerning the design of the fastening fixture 66 shown in FIG. 10,
